Traditional education focuses on teaching, not learning. It incorrectly assumes that for every ounce of teaching there is an ounce of learning by those that are taught. …

After lecturing to undergraduates at a major university, I was accosted by a student who had attended the lecture. After some complimentary remarks, he asked, “How long ago did you teach your first class?”

I responded, “In September of 1941.”

“Wow!” The student said. “You mean to say you have been teaching for more than 60 years?”

“Yes.”‘

“When did you last teach a course in a subject that existed when you were a student?”

This difficult question required some thought. After a pause, I said, “September of 1951.”

“Wow! You mean to say that everything you have taught in more than 50 years was not taught to you; you had to learn on your own?”

“Right.”

“You must be a pretty good learner.”

I modestly agreed.

The student then said, “What a shame you’re not that good a teacher.”
